Being a newbie I have been prone to clockwatching, even to the point of using a stop watch on my jobs....I have now got rid of that and now do not wear my watch during the day....this has made me a little more chilled about time, time, time , getting to the next job...blah, blah
When you take on a new job, take the extra couple of minutes to think about how to 'walk' the job, route hoses, ladders etc...
Cheers
Dave.
